Coding defects are errors in coding or logic that causes a program to malfunction or to produce incorrect or unexpected results. A program that contains a large number of bugs is said to be buggy. Reports detailing bugs in software are known as bug reports.
A software bug arises when the expected result does not match the actual results. It can also be an error, flaw, failure, or fault in a computer program. Most bugs arise from mistakes and errors made by developers, architects.
Defects are defined as the deviation of the actual and expected result of system or software application. When a developer or programmer during the development phase makes some mistake, then that turns into bugs that are called defects. The developers’ mistakes cause them.
Coding defect in a software product represents the inability and inefficiency of the software to meet the specified requirements and criteria and subsequently prevent the software application to perform the expected and desired to work.
Types of Defects
Logical defects are mistakes done in the implementation of the code. When the programmer does not understand the problem clearly or thinks in a wrong way, then such types of defects happen. Also, while implementing the code, if the programmer does not take care of the corner cases, then logical errors occur. It is related to the core of the software.
Interface defects mean the defects in the interaction of the software and the users. The system may suffer different kinds of interface testing in the forms of the complicated interface, unclear interface, or the platform based interface.
Arithmetic defects include the defects made by the developer in some arithmetic expression or mistake in finding the solution of such arithmetic expression. The programmer causes this type of error due to access work or less knowledge. Code congestion may also lead to arithmetic defects as a programmer is unable to watch the written code properly.
Performance defects are the defects when the system or the software application is unable to meet the desired and the expected results. When the order or the software application doesn’t fulfill the users’ requirements, then that is the performance defects. It also includes the response of the system with the varying load on the system.
Syntax defects mean a mistake in the writing style of the code. It also focuses on the small error made by the developer while writing the code. Often the developers do the syntax defects as there might be some little symbols escaped.
Multi-threading means running or executing multiple tasks at the same time. Hence in the multi-threading process, there is the possibility of complex debugging. In multi-threading processes, sometimes there is a condition of the deadlock.
To Wind Up
A coding defect is a condition in a software product that does not meet a software requirement, as stated in the requirement specifications. Likewise, end-user expectation which may not be specified but is reasonable. In other words, a defect is an error in coding or logic. It causes a program to malfunction or to produce incorrect or unexpected results.
